I have ones that are .010 larger than stock. I have heard that a wheel cylinder hone can work to ream out the hole in the axle, true? or would it be just as easy to remove axle and take to shop that will fit pins and bushings to spindles?

Taking the axle and spindles to the machine shop would be the perfect solution. The axle can be reamed in place if you have access to the proper tools. It sounds like you know the procedure on this operation already.

Someone will correct me, if I am wrong; but, if you do not have a reamer and a hydraulic press, you should take the axle off the truck and bring the axle and spindles to a machine shop (that has experience with fitting king pins).
1. The axle will have to be reamed (drilled and reamed at a specific angle) for the over-sized outer-diameter of the king pin.
2. The spindle bushings will have to be pressed into the spindles
3. The holes in the spindle bushings will have to be reamed to the size of the king pins.
4. Also, you might as well have the shop install the king pins, shims, and bearings (and grease the assembly).
1/2 ton bushings do not need to be reamed and the bushings are a looser fit into the spindles than on the larger trucks. However, the axle on a 1/2 ton would still have to be reamed (drilled & reamed?) for an over-sized king pin.

Just curious..why do you think you need oversize pins?

tclederman speaks truth. Just went through this process myself. Step 4 (having the shop install the pins and such) is a good idea but takes some of the fun out of it. Depends on how fed up you are at the time. My 58 had full floaters, but on the 49 1-ton they may only be press-fit.
Good Luck,

This is a job you can do yourself and the spiral wound bushings are twisted in and can adjust themselves and need no reaming. The pins are also groved and hold much much more grease. I used them on my truck and highly recommend them even though they are a bit pricey. | | |
